System Too Rich (Bank 2)

40 brands affected · Generic SAE J2012 description.

Key terms: Catalytic converter: cleans the exhaust gases · Oxygen sensor: measures oxygen in the exhaust gas · Mass air flow sensor: measures the air going into the engine · Bank 2: the side of the engine containing cylinder 2 · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

The engine is running rich on the second bank of cylinders, meaning there is too much fuel or not enough air in the mixture.

2Common causes

  1. Leaking fuel injector
  2. Faulty fuel pressure regulator
  3. Dirty mass air flow sensor
  4. Blocked air filter
  5. Faulty coolant temperature sensor
  6. Faulty oxygen sensor

3Can I drive?

Caution · drive with care

Usually safe to drive gently. Rich running wastes fuel and can damage the catalytic converter over time; have it checked soon.
